CO2 Absorbers / CO2 Breather Filters: The Necessity of CO2 Absorber / CO2 Breather Filter for water tanks

Water conductivity measurements are used to determine the content of impurities in water as a result of its interaction with carbon dioxide (CO2). In the semiconductor, pharmaceutical, food and beverages as well as in power generation industries the demineralized (DM) water in the tank is often exposed to carbon dioxide (CO2) from the air. Carbon dioxide increases DM water conductivity and creates pollutants in the form of metallic or salt impurities.

Dissolved CO2 from the atmospheric air in demineralized water causes an increase in conductivity and a decrease in pH relative to the expected values of 0.0550 mS / cm and 7.00 pH at 25°C. For example, the conductivity of demineralized water increases to about 1 mS/cm, and the pH drops to 5,7 when water is exposed to the air with CO2 concentration of 0,03%, which is a very low level for outside air. The carbon dioxide level in the atmospheric air is equal to 0,45% or even higher which is quite often the case nowadays.

In order to prevent external air CO2 from contacting the demineralized water in storage tanks, Alfaintek proposes to install CO2 removal systems on the vent nozzle of the tanks: CO2 Absorbers / CO2 Breather Filters.

Pumping water from reservoirs creates vacuum. As a result, atmospheric air begins to enter the reservoir through CO2 Absorbers / CO2 Breather Filters. When air passes through the CO2 Absorbers / CO2 Breather Filters, carbon dioxide (CO2) from the air is completely trapped and eliminated by the CO2 Absorbers / CO2 Breather Filters and air can enter the tank fully free of carbon dioxide. Thus CO2 Absorbers / CO2 Breather Filters prevent the increase of conductivity of demineralized water and the formation of metallic or salt impurities in DM water.
